Hi guys, 10 or so years ago I got the 1214 code so sent the EBCM into abs fixer , got it back and I installed it and all was well for a while until I got a different code (cant remember what it was now) , did some research and it sounded like it was the steering wheel sensor, i just put up with it for 10 years , until i decided to replace it 2 months ago and it got rid of that code.

About a month ago I got the 1214 again, I've cleaned the 3 main grounds in the engine bay , made sure the connections on the ebcm are good and given it a light tap with a hammer
.
Could the EBCM have gone bad again ?
Could the steering wheel sensor be related to the EBCM or just a coincidence?
Has any one else had to repair the EBCM twice?
appreciate any feed back.

Thanks .
Glenn.

 

I remember reading somewhere that the repair to the ebcm sometimes isn’t permanent. I would call abs fixer and see what they say.

 

Glenn,
ABS Fixer's C1214 repair to the EBCM was to replace a relay inside the EBCM. That is the only thing that can be repaired. The problem is the burned out relay is usually a symptom of the actual problem and not the problem itself. The relay supplies current to the pump motor in the Brake Pressure Modulator Valve (BPMV). Sometimes the stock relay just goes bad but a lot of times the problem is really excessive current draw due to a pump motor that is starting to go bad which then burns out the stock relay. ABS Fixer's relay is over sized for the application so when the repaired EBCM is installed back in the car it may supply sufficient current to the pump motor until the pump motor completely shorts out. C1214 represents insufficient voltage available to feed the motor and a low resistance increases current draw while lowering voltage.

I don't know if your EBCM is still good but one of the first things you need to do is check the resistance between the pump motor windings and the pump motor case. If that resistance is less than infinite the BPMV needs to be replaced along with maybe the EBCM. If the resistance of the pump motor circuit to it's case wasn't checked when the first repair was done you may have been just covering up the actual failure until it got so bad the update relay burned out or the voltage level dropped so low the pump motor couldn't operate.

I’m still curious what abs fixer says about this. Please post their response. While I’m sure the post above is well informed, this may be the only post of an ebcm repair failing and thus it’s very interesting.

 

Hi Bill, thanks for sharing your thoughts on it.
to be honest it sounds way above my knowledge and skill level, so I may have to put things back together and take the car to an auto electrician and I can show him your response to help him in the right direction. There are arent a heap of C5's here in New Zealand.

 

I've tried ringing ABS FIXER a couple of times but no answer, he may be on holiday, its difficult to call with the time difference of the USA and New Zealand.
